Setting lineups & pitching rotations for 31 teams... something like this was surely going to happen. Luckily, I caught it after game #12.
On my 1985-02 Cardinals team, Albert Pujols was drafted as my starting 3B, but since it's not his primary position, he was slotted in as a starting LF. Since Pujols is my only eligible 3B, sparky slotted Willie McGee as my starting 3B. I missed this until just now. Somehow, McGee played 65 error-free innings with one + play.
